Important Fitment Note: This impeller is designed for the Johnson F5B pump, NOT the larger F6B pump commonly used on Indmar engines. Most Indmar applications use the Johnson 09-812B impeller instead. Check the pump model engraved on your water pump cover plate and verify your impeller dimensions before ordering.

Maintenance Recommendation: Inspect your impeller regularly and replace it according to your engine manufacturer's recommended service schedule. Keeping a spare impeller onboard can help prevent unexpected downtime.
